Title: Gas mixing and diluting device
Inventor: MAO HAIBO
IPC: B01F23/10
Filed: 2021-08-13
Granted: 2021-10-14
Abstract: The present utility model belongs to the field of experimental apparatus, and specifically 
relates to a gas mixing and diluting device. The device comprises an injection unit including 
an injection cylinder and a feed mechanism, as well as a cylinder cap, an injection port, an 
injection tube, a clamping ring and a connecting sleeve; wherein the feed mechanism 
comprises a push rod located inside the injection cylinder, a piston is arranged at a front end 
of the push rod, an outer wall of the clamping ring is clamped with the cylinder cap, and an 
inner wall of the clamping ring is clamped with the push rod; one end of the connecting 
sleeve is connected to a one-way valve I, and the one-way valve I is connected to a reversing 
valve; the injection tube is in sealed connection to the one-way valve I, and the one-way valve 
I is in sealed connection to the reversing valve; the piston is matched with the injection tube, 
and the piston is provided with at least one circular groove. Continuous manual gas taking and 
injection are not required for the diluting device having the above-mentioned structure, and 
the whole gas diluting process is in a closed state. Since multiple sealing structures are 
provided in the above-mentioned device, it is not easy for gas to leak, and thus the result is 
more accurate in the preparation process of a gas standard curve.

Patent CH-652190-A5 (CH)
Inventor: WEBER ANTON
IPC: F22B31/00
Filed: 1981-04-23
Abstract: The fluidized bed is situated in a combustion chamber formed from evaporator tubes welded in seal-tight relationship and leading into a gas flue. The combustion chamber is connected to the gas flue via two inclined connecting wall surfaces. Heater tubes bent into an L-shape extend through the fluidized bed. Each shorter limb of the heater tubes extends substantially vertically while the other longer limb extends substantially horizontally. The horizontal limbs pass through a substantially vertical combustion chamber wall at the level of the fluidized bed and the vertical limbs pass through the free surface of the fluidized bed beneath the connecting wall surface. As a result of this arrangement of the heater tubes, the stresses therein due to uneven thermal expansion of the heater tubes remain within permissible limits.

Title: IC engines fuel preconditioning - using fuel preheating and expanding means prior to carburetor float bowl
IPC: F02M31/16
Filed: 1975-05-20
Abstract: In combination with an internal combustion engine having a circulating liquid coolant system that is thermostatically controlled to limit temp. of liquid coolant to a predetermined max. value, a carburetor for supplying a combustible mixture of fuel and air to the engine, and including a float bowl for holding a predetermined volume of liquid fuel, means for supplying a flow of liquid fuel under pressure, and a single fuel conduit connecting the fuel supplying means to the float bowl of the carburetor. A fuel preheating and expanding device comprises a cylindrical fuel expansion chamber inserted in the fuel conduit adjacent to the carburetor, the ratio of the cross sectional area of the expansion chamber to the flow area of the fuel conduit being at least ten and the volume of the expansion chamber being of the order of the volume of the carburetor float bowl. An outer cylindrical shell surrounds the fuel chamber in radially spaced relation, the shell being closed by two end walls and having an inlet pipe near one end and an outlet pipe near the other end, the inlet and outlet pipes being connected to high and low pressure regions, respectively, of the circulating liquid coolant system for providing a flow of liquid that has been heated in the engine through the space between the expansion chamber and the outer shell from the inlet pipe to the outlet pipe. There is also a means for restricting one point of the flow path of heated liquid engine coolant through said space to a predetermined cross-sectional area related to the maximum coolant temperature and the surface area of the expansion chamber to prevent heating the fuel to a temperature at which its vapour pressure exceeds the absolute pressure at the inlet to the carburetor float bowl.
Patent CH-588870-A5 (CH)
Title: Catheter with central and interior fluid tubes - has porous section to localise fluid discharge and exterior balloon to limit penetration
IPC: A61F2/958
Filed: 1975-05-22
Abstract: The clinical catheter comprises a central tube in which two smaller tubes are situated. The two small diameter tubes introduce medicine into the catheter. Two canals join the central tube near its base which is covered in a plastic coating which extends the length of the tube up to the inflatable upper balloon section. This coating allows the entry to the catheter to be blocked off. A porous section of the central tube located halfway up its length is situated between a shut-off ring and the tube end. This localises the fluid discharge while an exterior balloon limits the depth at which the catherer may be introduced.

Title: Apparatus for ringless spinning
Inventor: TIKHONOV VALENTIN NIKITOVICH
IPC: D01H4/10
Filed: 1979-11-02
Abstract: A rotatable spinning chamber (1), which is designed as a frustoconical hollow cone and which has a groove (3) is provided. Each portion (c, d) of the groove is at a different distance (1, 11) from the axis (0) of the spinning chamber (3). The yarn is thereby set in vibration and consequently the coarse and heavy impurities are decomposed into finer and lighter particles. These are carried away through orifices (9) together with the main mass of impurities. <IMAGE>

Granted: 2004-06-01
Abstract: On assemble un compresseur à volutes (20) par ajustement à force de l'unité de pompe (22) et du palier inférieur dans le boîtier (38) externe généralement cylindrique. On augmente la force de retenue de l'ajustement à force en munissant à la fois la boîte de manivelle (24) et le support de palier de parties cylindriques. La force de retenue de l'ajustement à force est donc appliquée sur toute la périphérie des éléments. La structure améne de préférence le boîtier (38) externe au-delà de son point de déformation plastique, augmentant ainsi également la force de retenue. On peut utiliser de cette manière le procédé relativement simple d'ajustement à force pour assembler le compresseur à volutes (20) tout en obtenant encore une force de retenue acceptable.

Title: Forming yarn hanks
IPC: B65H54/56
Filed: 1970-05-11
Granted: 1971-03-05
Abstract: The yarn is fed via a reciprocating guide to a hank support, defined by a circular arrangement of axial rods carried on radial arms extending from a rotating shaft, onto which the hank is wound, and the guide is mounted on a carriage which is moved (pref. by an endless screw) axially with respect to the hank, so that the start-in turns of successive layers are displayed axially with respect to one another. This prevents the starting turns from crossing one another and causing a build up of yarn, thus allowing the yarn to be wound off the support without becoming entangled.
